Spigelian hernia: a rarity

Spigelian hernias are rare and generally difficult to diagnose because of their location and vague non-specific symptoms. They are situated between the muscular layers of the abdominal wall and can be easily overlooked because of abdominal obesity. The diagnosis has been considerably aided by the introduction of ultrasonography and computed tomography (CT). These hernias require surgical treatment. We report a 31 years old patient from the Sultan Qaboos University Hospital who presented with colicky lower abdominal pain associated with a tender swelling above and lateral to the inguinal canal. A diagnosis of Spigelian hernia was made and confirmed on exploration. The hernia was reduced and the defect repaired. Her recovery was uneventful.
